I decided to repaint the build a figure to make it look more screen accurate. It was hard to grab details from movie stills so I went with pictures from the hot toys figure. HA!

I painted the whole thing black with a couple light layers, then a couple light layers of silver, then you guessed it, a couple light layers of clear red/yellow where it needed it. All the coloring credit goes to the author of the guide posted here about metallic colors.
